What's the easiest way to make a music video out of photos? Thanks!

PhotoStage by NCH Software is a freeware product available to make movies from photos. You can add music at background, animations to the photos, write text on photos and add transition effects from one photo to other. I have used this tool to prepare a video for my baby showering gathering. You have option to export video at the required quality of pixels. I have played it on 50 inch TV, so I have exported in super HD. This tool is a good option when you don't want to spend on licence costs.
